Rapid development in industrialization and urbanization results in significant increases in the volume of greenhouse gases such as carbon dioxide (CO2), methane (CH4), and other gases and leads to global warming. The capture and efficient conversion of CO2 into chemicals and fuels is a sophisticated process and has gained significance in reducing the concentration of CO2 present in the environment. CO2 is highly stable and is utilized as a catalyst in the synthesis of chemicals such as methanol, salicylic acid, dimethyl carbonate, and cyclic carbonates. Carbon derivatives based adsorbants are considered to be versatile materials used to capture CO2 due to their similar physical and chemical properties. Photoelectrochemical conversion of CO2 is considered to be an artificial photosynthesis employing different wide band gap semiconductors, and produces chemicals/fuels such as formic acid, methane, ethanol and ethanol. In this chapter, we report the capture and conversion of CO2 into chemicals and fuels by different techniques such as photoelectrochemical, photocatalysis, electrocatalysis, thermo-catalysis, and biochemical techniques.
